SEW MOVIDRIVE bus positioning

Reference offset: Set the offset of the machine zero point relative to the reference point.

Reference operation type (0-7):

Type 0: No reference operation, reference position is the zero pulse to the left of the current position

Type 1: Reference cam left edge

Type 2: Reference cam right edge

Type 3: Right limit switch (without reference to cam)

Type 4: Left limit switch (without reference to cam)

Type 5: No reference operation, reference position is the current position (no zero pulse)

Type 6: Reference cam left edge (similar to Type 1)

Type 7: Reference cam right edge (similar to Type 2)

Slope time: Acceleration and deceleration time in seconds for jog mode and automatic mode

Speed limit: maximum speed in automatic mode, maximum speed in jog mode, maximum speed in speed controller (P302). The latter two should be at least 10% smaller than P302

Click "Next>>" and save the settings. After the download window appears, click<Download>to write all parameters to the inverter and start the IPOS program.

After downloading, the program asks if to switch to the monitor (Figure 29). Select 'Yes' to enter the bus positioning monitor (Figure 30), where diagnosis and control can be performed.

3.3 Operation mode (selected through control word PO1 bit 11/12)

Mode bit 11 bit 12

Invalid 0 0

Jogging mode 1 0

Reference mode 0 1

Automatic mode 1 1

3.3.1 Reference Mode (Bit 11=0, Bit 12=1)

Premise: DI00=1, DI01=1, and PO1:1=1, PO1:2=1

Start the reference run with PO1:8=1 (keep it at 1 until complete)

The driver moves towards the reference cam at reference speed 1, switches to reference speed 2 when encountering the cam, and stops and locks its position when leaving the cam

When the status word PI1:2 (IPOS reference) is set to 1, PO1:8 can be revoked

After the reference is completed, it can be switched to automatic mode

3.3.2 Jogging mode (bit 11=1, bit 12=0)

Used for maintenance or manual adjustment

PO1: 9=1 → Forward turning jog; PO1:10=1 → Reverse jog

The jogging speed is determined by the set value of PO2

3.3.3 Automatic mode (bit 11=1, bit 12=1)

PO2 provides the set speed, PO3 provides the target position

PO1: 8=1 Start positioning (must remain at 1)

After reaching the target position, PI1:3 (Set position) is set to 1, and the driver position is locked

If PO1:8 remains at 1 and PLC updates PO3, the driver immediately moves to the new position

3.4 Parameter List

Automatically set the following parameters after startup (cannot be manually modified):

3.5 Remove the limit switch

When the drive collides with the limit switch (DI04 or DI05=0), PI1:5 (fault) is set to 1, and the drive comes to an emergency stop. Removal steps:

Set the operating mode to jog mode (PO1:11=1, PO1:12=0)

Set PO1:6 (fault reset) to 1, PI1:5 to 0

Maintain PO1:6=1, the driver automatically moves out in the opposite direction at a speed of 100 rpm

After removal, restore DI04/DI05 to 1, set PO1:6 to 0, and then switch back to the desired mode

Operation and maintenance

4.1 Fault Information

Fault memory P080 stores the last 5 faults (t-0 latest). When a fault occurs, the following data is stored: fault code, I/O status, operating status, inverter status, radiator temperature, speed, output current, active current, utilization rate, DC bus voltage, power hours, enable hours, parameter group, and motor utilization rate.

Shutdown response:

Immediately disconnect: output stage high resistance, brake immediately closes

Quick parking: Reduce speed according to the stopping slope t13/t23, and close the brake after reaching the stopping speed

Emergency stop: Reduce speed according to the emergency slope t14/t24, and close the brake after reaching the stopping speed

Reset method:

Power on again after power outage (main contactor disconnected for at least 10 seconds)

Through binary input DI02 (configured as reset function)

Reset button in MOVITOOLS Manager

Press the<E>key (P840) on the DBG11A keyboard

4.2 Specific fault codes

Possible causes and countermeasures for fault code name response

07 DC bus overvoltage immediately disconnected, deceleration time is too short, brake resistor open circuit extends slope, check brake resistor wiring

08 n - Immediately disconnect the overload, phase loss, and encoder wiring errors to reduce the load, and check the encoder A/A and B/B swapping

Immediately disconnect the encoder cable for poor shielding, disconnection, and short circuit in case of encoder malfunction. Check the continuity and wiring of the shielding layer
